NACR-849 New Employee Sayu Nanahara Pretends to Be Asleep and Later Blackmails

New employee Sayu Nanahara misses the last train at a company drinking party and stays over at a male colleague's place, knowing his wife is away. He gropes her while she is asleep, then inserts himself, thinking she is unaware. Later, she visits him on a day off and threatens him about that night, toying with him as a devilish new employee.
